我已经指定在我的构建路径中使用Spring版本3.1.0，但它会自动转换为Spring 3.0.5.RELEASE。我猜它是因为Spring + Jersey依赖。当我尝试使用mvn tomcat:run启动服务器时，出现以下异常：

EnvironmentCapable.class文件存在于spring-core-3.1.0.RELEASE.jar中。我手动将jar添加到我的构建路径但仍然得到相同的异常。我正在使用Eclipse Indigo。请指教。

Answer 1

如果您在pom.xml内查看jersey-spring-1.8.jar，则会看到此内容，

    <properties>
        <spring20-release-version>2.0.5</spring20-release-version>
        <spring25-release-version>[2.5.2,3)</spring25-release-version>
    </properties>

这意味着，jersey-spring-1.8强制您只使用弹簧版本至3。我认为这是问题所在。

Answer 2

<version>${org.springframework.version}</version>来自哪里？它没有被定义为POM文件中的属性，所以我的猜测是这个属性来自其中一个依赖项并接管你的3.1.RELEASE（提示：看看jersey-spring依赖项）不要使用属性来定义版本！使用Maven的＆lt; DependencyManagement＆gt;用于控制隐式和显式版本的部分！我建议你使用依赖范围provided

Answer 3

问题在于POM中的LDAP依赖性。它正在将3.0.5版本集成到构建路径中。 mvn dependency:tree变得显而易见。

正如上面提到的 aviad ，将provided添加到LDAP依赖项工作正常。我将exclusions添加到依赖项中，这非常繁琐。：）
